Description of Heavy Copper Printed Circuit Board Feature:

1. Carrying high current

When the line width is constant, increasing the copper thickness is equivalent to increasing the cross-sectional area of the circuit, so thickening the copper foil can enable the circuit board to carry a larger current.

2. Reduce thermal strain

The conductivity coefficient of copper foil is small (the conductivity coefficient is the resistivity; metal conductors are divided into the order of conductivity: silver→copper→gold→aluminum→tungsten→nickel→iron.). In the case of passing a large current, the temperature rise of the copper foil is small, so the thick copper plate can reduce the heat generation, thereby reducing thermal strain.

3. Good heat dissipation

Because copper foil has high thermal conductivity, the use of thick copper plates can play an important role in terms of heat dissipation.
